| 106 | =head1 NAME |
| 107 | |
| 108 | I18N::Langinfo - query locale information |
| 109 | |
| 110 | =head1 SYNOPSIS |
| 111 | |
| 112 | use I18N::Langinfo; |
| 113 | |
| 114 | =head1 DESCRIPTION |
| 115 | |
| 116 | The langinfo() function queries various locale information that can be |
| 117 | used to localize output and user interfaces. The langinfo() requires |
| 118 | one numeric argument that identifies the locale constant to query: |
| 119 | if no argument is supplied, C<$_> is used. The numeric constants |
| 120 | appropriate to be used as arguments are exportable from I18N::Langinfo. |
| 121 | |
| 122 | The following example will import the langinfo() function itself and |
| 123 | three constants to be used as arguments to langinfo(): a constant for |
| 124 | the abbreviated first day of the week (the numbering starts from |
| 125 | Sunday = 1) and two more constants for the affirmative and negative |
| 126 | answers for a yes/no question in the current locale. |
| 127 | |
| 128 | use I18N::Langinfo qw(langinfo ABDAY_1 YESSTR NOSTR); |
| 129 | |
| 130 | my ($abday_1, $yesstr, $nostr) = map { langinfo } qw(ABDAY_1 YESSTR NOSTR); |
| 131 | |
| 132 | print "$abday_1? [$yesstr/$nostr] "; |
| 133 | |
| 134 | In other words, in the "C" (or English) locale the above will probably |
| 135 | print something like: |
| 136 | |
| 137 | Sun? [yes/no] |
| 138 | |
| 139 | but under a French locale |
| 140 | |
| 141 | dim? [oui/non] |
| 142 | |
| 143 | The usually available constants are |
| 144 | |
| 145 | ABDAY_1 ABDAY_2 ABDAY_3 ABDAY_4 ABDAY_5 ABDAY_6 ABDAY_7 |
| 146 | ABMON_1 ABMON_2 ABMON_3 ABMON_4 ABMON_5 ABMON_6 |
| 147 | ABMON_7 ABMON_8 ABMON_9 ABMON_10 ABMON_11 ABMON_12 |
| 148 | DAY_1 DAY_2 DAY_3 DAY_4 DAY_5 DAY_6 DAY_7 |
| 149 | MON_1 MON_2 MON_3 MON_4 MON_5 MON_6 |
| 150 | MON_7 MON_8 MON_9 MON_10 MON_11 MON_12 |
| 151 | |
| 152 | for abbreviated and full length days of the week and months of the year, |
| 153 | |
| 154 | D_T_FMT D_FMT T_FMT |
| 155 | |
| 156 | for the date-time, date, and time formats used by the strftime() function |
| 157 | (see L<POSIX>) |
| 158 | |
| 159 | AM_STR PM_STR T_FMT_AMPM |
| 160 | |
| 161 | for the locales for which it makes sense to have ante meridiem and post |
| 162 | meridiem time formats, |
| 163 | |
| 164 | CODESET CRNCYSTR RADIXCHAR |
| 165 | |
| 166 | for the character code set being used (such as "ISO8859-1", "cp850", |
| 167 | "koi8-r", "sjis", "utf8", etc.), for the currency string, for the |
| 168 | radix character used between the integer and the fractional part |
| 169 | of decimal numbers (yes, this is redundant with POSIX::localeconv()) |
| 170 | |
| 171 | YESSTR YESEXPR NOSTR NOEXPR |
| 172 | |
| 173 | for the affirmative and negative responses and expressions, and |
| 174 | |
| 175 | ERA ERA_D_FMT ERA_D_T_FMT ERA_T_FMT |
| 176 | |
| 177 | for the Japanese Emperor eras (naturally only defined under Japanese locales). |
| 178 | |
| 179 | See your L<langinfo(3)> for more information about the available |
| 180 | constants. (Often this means having to look directly at the |
| 181 | F<langinfo.h> C header file.) |
| 182 | |
| 183 | Note that unfortunately none of the above constants are guaranteed |
| 184 | to be available on a particular platform. To be on the safe side |
| 185 | you can wrap the import in an eval like this: |
| 186 | |
| 187 | eval { |
| 188 | require I18N::Langinfo; |
| 189 | I18N::Langinfo->import(qw(langinfo CODESET)); |
| 190 | $codeset = langinfo(CODESET()); # note the () |
| 191 | }; |
| 192 | if (!$@) { ... failed ... } |
| 193 | |
| 194 | =head2 EXPORT |
| 195 | |
| 196 | By default only the C<langinfo()> function is exported. |
| 197 | |
| 198 | =head1 SEE ALSO |
| 199 | |
| 200 | L<perllocale>, L<POSIX/localeconv>, L<POSIX/setlocale>, L<nl_langinfo(3)>. |
| 201 | |
| 202 | The langinfo() is just a wrapper for the C nl_langinfo() interface. |
